  The new BL06-XAIRA mi­cro­fo­cus macro­mol­e­c­u­lar crys­tal­log­ra­phy beam­line at ALBA syn­chro­tron is cur­rently under com­mis­sion­ing and fore­seen to enter into user op­er­a­tion in 2024. The aim of XAIRA is to pro­vide a 4-14 keV, sta­ble, high flux beam, fo­cused to 3×1 µm2 FWHM. The beam­line in­cludes a novel mono­chro­ma­tor de­sign com­bin­ing a cry­ocooled Si(111) chan­nel-cut and a dou­ble mul­ti­layer dif­fract­ing op­tics for high sta­bil­ity and high flux; and new mir­ror ben­ders with dy­nam­i­cal ther­mal bump and fig­ure error cor­rec­tors. In order to re­duce X-ray par­a­sitic scat­ter­ing with air and max­i­mize the pho­ton flux, the en­tire end sta­tion, in­clud­ing sam­ple en­vi­ron­ment, cryostream and de­tec­tor, is en­closed in a he­lium cham­ber. The sub-100nm SoC dif­frac­tome­ter, based on a unique he­lium bear­ing go­niome­ter also com­pat­i­ble with air, is de­signed to sup­port fast os­cil­la­tion ex­per­i­ments, raster scans and he­li­cal scans while al­low­ing a tight sam­ple to de­tec­tor dis­tance. The beam­line is also equipped with a dou­ble on-axis vi­su­al­iza­tion sys­tem for sam­ple imag­ing at sub-mi­cron res­o­lu­tions. The gen­eral sta­tus of the beam­line is pre­sented here with par­tic­u­lar de­tail on the in-house fully de­vel­oped end sta­tion de­sign.

In this paper we pre­sent the newly built beam­line MIN­ERVA, an X-ray fa­cil­ity at the ALBA syn­chro­tron. The beam­line has been de­signed to sup­port the de­vel­op­ment of the X ray ob­ser­va­tory ATHENA (Ad­vanced Tele­scope for High En­ergy As­tro­physics). MIN­ERVA will host the nec­es­sary metrol­ogy equip­ment to in­te­grate the stacks pro­duced by co­sine in a mir­ror mod­ule (MM) and char­ac­ter­ize their op­ti­cal per­for­mances. The op­ti­cal and me­chan­i­cal de­sign is based on the XPBF 2.0 from the Physikalisch-Tech­nis­che Bun­de­sanstalt (PTB), at BESSY II al­ready in use to this ef­fect and its con­struc­tion is meant to sig­nif­i­cantly aug­ment the ca­pa­bil­ity to pro­duce MM. The de­vel­op­ment of MIN­ERVA has ad­dressed the need for im­proved tech­ni­cal spec­i­fi­ca­tions, over­come ex­ist­ing lim­i­ta­tions and achieve en­hanced me­chan­i­cal per­for­mances. We de­scribe the de­sign, con­struc­tion process and im­ple­men­ta­tion of Min­erva that lasted three years. Even though the beam­line is still under a com­mis­sion­ing phase, we ex­pose tests and analy­sis that have been re­cently per­formed, re­mark­ing the im­prove­ments ac­com­plished and the chal­lenges to over­come, in order to reach the op­er­a­tional readi­ness for the mir­ror mod­ules mass pro­duc­tion.
